i SAGINAW, MICHIGAN, Av CORPORATION OF NEW YORK SHADE ROLLERVApplication filed August 25, 1931. Serial No. 559,227.

This invention relates toV shade roller construction, andrparticularlyto the winding mechanism thereof. Y

One object of the invention is to provide a simple and substantialwinding mechanism, made up of a minimum number of parts, which will notget out of-order; which will be cheap to manufacture, and which can bereadily installed and assembled.

Another object is to provide new and novel means for anchoring the outerend-of the spring, so that it'can be readily positioned or removed, andwhich when the rollery is assembled, is locked in position.`

` A further object is to4 provide a large .and

rugged self centering bearing of simple construction, which will runaccurate and true, and which will not become sloppy with long use. v

A still further object is to `provide a winding mechanism so constructedand :assembled, that all parts remain in their true assembled workingrelation, regardless of severe blows or ars caused by hammer blows whengudgeons. are inserted, or when the roller repeatedly falls on theprojecting spear.

` `The above Vand other objects will appear as the specificationprogresses, reference being had to the accompanying drawing in which Ihave shown the preferred embodi- V ment of my invention, and in whichlike ref- @rence numerals indicatelike parts throughvout the severalnviews thereof.

In the drawing: i j j i Fig. 1 is a part sectional side view of one endof a shade roller constructedin accordance with my invention. A

Fig. 2 is an end view thereof.

Fig. 3 is a longitudinal .sectional view through the winding mechanism.

Fig. 4 is a detail -endview illustrating the -manner Vof anchoringtheone end of the spring. V

Fig. 5 is a view showing t-he various-parts in spaced apart relation. A

Fig. 6" is a detail'part sectional side Yview of the spindle and spindleferrule, the dotted lines showing the position of the `prongs be- Yforebeing forced into the spindle. V

Fig. 7 is an end view of the spindle ferrule.

Referring now to the drawing in which I have shown the preferredembodiment of my invention, the numeral 5 indicates the body of theroller which can be of any suitable material, wood being most common inuse, this is centrally bored as shown at 6, and is adapted toaccommodate the conventional spring and spindle, 7 and 8 respectively,the inner end of the spindle having a saw cut as shown at 9, and the endof the spring is shaped to lit and seat thereon, the opposite end beingformed with a loop 10 for a purpose to be later described. Y

A ferrule member 11 fits over the outer end of the spindle, the headbeing reduced and projecting slightly beyond the end thereof, said headbeing formed with arectangular opening 12 adapted to accommodate the endof the conventional spear 13,which projects into the end of the spindle,the ferrule being provided with spaced apart legs or prongs 14 (shown indotted lines in Fig. 7)v and is adapted, when the ferrule is placed inposition, to be forced into the spindle to hold the ferrule tightly inplace.

A spool bearing 15 is ournaled on the ferrule member 11 and is formedwith a reduced neck portion 16 which, when assembled, projects into acentrally disposed opening 17 provided in a spool 18 and is solidlycrimped over the edge thereof forming a solid unit therewith, the innerend of said spool bearing fitting over the ferrule member 11 and isformed with spaced apart laterally project- 'ing wings 19 for a purposeto be presently ears being adapted to pierce and be embedded in theroller when the mechanism is assembled.

A ratchet (not shown) is mounted on the spear directly adjacent theturned end of the spool bearing and the usual diametrically oppositepawls' (not shown) are .pivotally mounted on the spool by means ofrivets 24, and are adapted to engage the ratchet in the usual manner, ahub 25 being mounted on the spear, and is interposed between the ratchetand the shoulder 26 of said spear, said hub having a centrally disposeddished center tion 27 of a size to receive the head of the spear. Aerrule 28 fits over the end of the roller in the usual manner, the innerend being crimped to engage the Wood as shown.

ln practice the spool 18 is iirst formed to shape and the pawls 23 aremounted thereon, vthe spool bearing 15 is then secured to the spoolforming a unit therewith, l then take the spear and assemble the hub,ratchet, spool, and spindle ferrule thereon, and then force the end ofthe spear into `the spindle, sWedging the spear in the 'ferrule Thespring 7 is then placed in position, the one end being anchored inthesaw cut 9, the opposite looped end being threaded behind the Wings 19,and the loop l() will then be locked behind the ears 2l, and as theWinding unit is mounted in the bore of the roller, these ears togetherWith the looped end of the spring will pierce the Wood and lock the endof the spring securely in position. To detach, it is merely necessary toremove the roller, bend the end of the spring to clear the ears, and itcan be easily unwound from the bearing.

I Wish to direct particular attention to the fact that the generalassembly absolutely eliminates the possibility of the mechanism becomingsloppy so that the pawls do not engage at all times; there can be noendwise movement of the ratchet Without a correspending movement of thespool on which the paivls are mounted; the mechanism operates smoothlyand easily, is evenly balanced, and Will Wear for an indefinite lengthof time.

From the foregoing description it Will'be obvious that I have perfecteda very simple, substantial, and economical Winding mechanism for shaderollers.

lVhat I claim is l. A shade roller comprising a. body, a spindleextending thereinto, a spool mounted on said spindle and secured to saidbody, and a spring anchored to one end of the spindle, the opposite endof said spring engaging said spool and being embedded and anchored inthe end of the roller body when the roller is assembled.

2. A shade roller comprising a body, a spindle extending into said body,a spool rotatably mounted thereon, a spool bearing secured to the spool,a spring mounted on the spindle and anchored to one end thereof, theopposite end being threaded on the spool bearing, and embedded andanchored in the end of the roller body when the roller is assembled.

3. A shade roller comprising a body, a spindle yextending thereinto, aspool mounted 4on the spindle, a spool bearing rigidly secured theretoand havingr Wings projecting` laterally therefrom, a spring mounted onthe spindle, one end being anchored thereto, the opposite end beingthreaded behind said Wings, and means on the spool for preventing theunwinding of the threaded end of said spring during the assembling ofthe roller.
